Out of all of Google’s close to $1 billion in clean power projects, turning biomass into energy seems like the least relevant technology to Google’s core business. But Google has made a few small investments into biomass projects, including a hog waste to energy project. Read more »
The momentum right now in cleantech is as much about connectivity and how it can drive energy efficiency as it is about advancing sources of renewable energy. And as the web and mobile connectivity change our consumer experiences, the opportunities to redefine cleantech are rich, and they are already happening. This research note examines the cleantech space in that context and analyzes the car-sharing, home-energy-management and smart-grid sectors and their relevant companies to see how connectivity will play into their future endeavors. Companies mentioned in this report include RelayRides, Opower, Silver Spring Networks and Nest. For a full list of companies, and to read the full report, sign up for a free trial.

Connectivity changes everything. That’s the credo driving just about every corner of our day-to-day lives. As human beings, we are now connected to one another through not just our social networks but also our cars, the books we read, the albums we download and even our own health and wellness habits (to name just a few areas). With that in mind, GigaOM Pro has singled out certain areas in the technology industry where we see this shift to constant connectivity taking place most drastically. Read more at GigaOM Pro »

Is the greentech industry headed for a breakout year or is it retrenching for hard times to come? The first three months of 2011 provided evidence that could support both assertions, with a big rise in venture capital investment and a big drop-off in global energy financing. Solar power remained the largest green technology sector in terms of venture capital investment, while in the world of electric vehicles, GM’s Chevy Volt hybrid and Nissan’s all-electric Leaf — the first two mainstream plug-in vehicles — hit the showroom floors in significant numbers. Meanwhile the smart grid sector’s relative dearth of VC investment was more than made up for by the massive round of acquisitions. Companies mentioned in this report include NRG Energy, Microsoft, Silver Spring Networks, Tesla and BrightSource Energy.

Data centers are a critical component of many businesses these days, but because of the amount of electricity they consume, they are extremely expensive to run. However, a great deal can be done both to cut costs and reduce their environmental footprint, simply by making them more energy efficient. Online technologies and applications are creating skyrocketing demand for new data centers, and most enterprises are now seeking “greener” solutions, both in their own facilities, and in the facilities with which they do business. This report looks at innovations in green data center design and identifies key players — from major data center operators to startups solving specific issues — leading the charge. Read more »
